JIS A 5015:2018 PDF Download

The JIS A 5015:2018 standard specifies the requirements for iron and steel slag used in road construction. The standard encompasses both blast furnace slag, produced during the manufacturing of pig iron, and steelmaking slag, produced during the manufacturing of steel. Blast furnace slag can further be categorized as air-cooled or granulated, depending on the cooling method used. Steelmaking slag can be classified as convertor-system slag or electric furnace-system slag, depending on the steel manufacturing process.

Iron and steel slag for road construction can be produced either from a mixture of blast furnace slag and steelmaking slag or individually. It can be used as a base course material in road construction, or as an aggregate in hot laid asphalt mix or bituminous stabilization. This standard ensures that the iron and steel slag used in road construction meets the required criteria and performance standards to ensure the desired quality and durability of the road.
